Avalanche Summary

Small avalanches are still possible under low hazard and can have serious consequences on steep features. Continue to practice good travel habits in avalanche terrain.

Observations have been limited. Please consider sharing your observations through the Mountain Information Network.

Snowpack Summary

Wind-affected snow covers most open and exposed areas. If you brave the cold, isolated pockets of soft snow may hide in sheltered lee features at upper elevations.

A relatively uniform snowpack is reported for White Pass: 10 to 20 cm of snow over a supportive crust. The remainder of the snowpack has no layers of concern. Snowpack depths range from about 100 to 180 cm.
